Is this a stupid strategy?

On tradingview, there’s an indicator called “lorentzian classification,” that’s known for being scarily accurate. I use it on QQQ, and if the most recent marker is red, I full port FNGD (-3x big tech) and if the most recent marker is green, I full port FNGU (3x big tech). I use these instead of TQQQ and SQQQ since the fang ETFs tend to be more volatile, while still being correlated.
